    MICHAEL GREGORY PETTY, Appellant
    V.
    THE STATE OF TEXAS, Appellee
    On Appeal from the 351st District Court
    Harris County, Texas
    Trial Court Case No. 1271999 & 1272000
    OPINION
    Following a joint trial on two separate indictments, a jury found appellant
    Michael Gregory Petty guilty of two offenses of intoxication manslaughter and
    further found that he had used a deadly weapon, namely, a motor vehicle, during
    the commission of each offense. 1 The jury assessed punishment at 20 years’ in
    prison for each offense. The State filed a motion to cumulate the sentences, and
    the trial court ordered the sentences to be served consecutively. 2
    Appealing each judgment of conviction, Appellant raises two identical
    issues in each appeal. Appellant (1) claims that he received ineffective assistance
    of counsel during trial, and (2) he challenges the sufficiency of the evidence to
    support the court costs assessed against him by the trial court.
    We affirm in each appeal.
    Background
    Midday, on July 26, 2010, Appellant was speeding down Interstate 45 when
    he lost control of his pickup truck. Appellant’s truck collided with a pickup truck
    driven by Manuel Portillo in which Cristo Alfonso was a passenger. The collision
    caused Portillo’s truck to flip and roll a number of times. The truck’s top was
    flattened, and Portillo’s head was pinned between the driver’s door and the roof.
    During the rollover, Alfonso had been ejected from the vehicle, landing in the
    middle of the freeway. Both Portillo and Alfonso died as a result of the injuries
    each sustained in the crash.

    2
    Before the crash, other motorists had seen Appellant speeding down the
    freeway, traveling 80 to 90 miles per hour in a 65-mile-per-hour zone. The
    motorists had been alarmed by Appellant’s speed and erratic driving. They saw
    Appellant changing lanes, zigzagging from one side of the freeway to the other,
    and darting between cars. When he approached slower traffic ahead of him in the
    far left lane, Appellant slammed on his brakes. He then shot to the right across all
    lanes of the freeway. Appellant lost control of his truck, and it hit the back left
    panel of Portillo’s vehicle. The force of the collision caused Portillo’s truck to flip
    and then roll side-over-side, coming to rest on the grassy shoulder of the freeway.
    Appellant was not injured in the collision. A number of the motorists who
    had witnessed the crash stopped on the freeway. One of the motorists approached
    Appellant. He noticed that Appellant was moving and speaking slowly. Appellant
    was also repeating himself, saying that his accelerator had stuck.
    Officer D. Egdorf, a certified drug recognition expert with the Houston
    Police Department, arrived at the scene to evaluate Appellant for signs of
    intoxication. Appellant told Officer Egdorf that he had not drunk any alcohol but
    stated that had taken a prescription medication, topiramate, about three hours
    earlier. Appellant said that he had been prescribed topiramate for his migraine
    headaches and had been taking the medication for a couple of weeks. He stated
    that he had been to the hospital the day before and had gotten a new prescription
    3
    for topiramate. He told the officer that the bottle of topiramate was in his truck.
    Appellant said that the prescription directed him to take three topiramate pills a
    day.
    Appellant also told Officer Egdorf that the label on the prescription bottle
    warned not to drive while taking topiramate. Appellant said that he had taken his
    girlfriend to work at a nearby restaurant that morning after taking the topiramate
    and then waited at the restaurant until the effects of the topiramate had worn off so
    that he could drive. He stated that his doctor had told him that the effects should
    wear off after two hours.       Appellant indicated that he did not feel that the
    topiramate affected his ability to drive.
    While at the scene, Officer Egdorf administered four field sobriety tests to
    Appellant: the Horizontal the Gaze Nystagmus (HGN), the one-leg stand, the walk-
    and-turn, and the Rhomberg. Appellant’s performance of the tests was recorded on
    the camera in Officer Egdorf’s vehicle.
    Officer Egdorf first administered the HGN test to Appellant. Officer Egdorf
    observed that Appellant displayed all “six clues” during the test.          Each of
    Appellant’s eyes showed (1) lack of smooth pursuit, (2) nystagmus or an
    involuntary jerking movement at maximum deviation, and (3) onset of nystagmus
    before forty-five degrees. This indicated to Officer Egdorf that Appellant was
    intoxicated.
    4
    Officer Egdorf then had Appellant perform the Rhomberg test in which
    Appellant was instructed to tilt his head back, close his eyes, and estimate thirty
    seconds. When Appellant indicated that 30 seconds had passed, 46 seconds had
    actually passed. Appellant’s failure to accurately estimate 30 seconds indicated a
    delay in Appellant’s reaction time and further indicated to Officer Egdorf that
    Appellant was intoxicated.
    Officer Egdorf also administered the one-leg-stand test and the walk-and-
    turn test. Appellant displayed one clue for intoxication when he swayed during the
    one-leg-stand test. Appellant displayed four clues for impairment during the walk-
    and-turn test. He used his arms for balance, he stopped walking, he failed to walk
    heel to toe, and he made an improper turn. Based on Appellant’s performance on
    the field sobriety tests, particularly the HGN test, Officer Egdorf believed
    Appellant to be intoxicated.
    In addition to Appellant’s performance on the tests, Officer Egdorf observed
    other behaviors by Appellant that further indicated to him that Appellant’s mental
    faculties were impaired.       Appellant interrupted Officer Egdorf while he was
    instructing Appellant how to perform the field sobriety tests. And Appellant had
    difficulty following the instructions. Appellant’s statements regarding what the
    cause of the crash may have been continued to shift as he and Officer Egdorf
    spoke. Appellant told Officer Egdorf that, before the collision, a vehicle on the
    5
    freeway traveling in front of him was “brake checking,” meaning the vehicle’s
    driver was tapping the brakes to send a message to another driver that the other
    driver needed to slow down. Appellant also told the officer that his engine had
    been revving. He mentioned that there had been a recall by the manufacturer of his
    truck regarding the floor mats. Appellant also told Officer Egdorf that he had
    cheap tires on the truck.
    Based on Appellant’s performance of the field sobriety tests and his
    interaction with Appellant, Officer Egdorf arrested Appellant for driving while
    intoxicated. Officer Egdorf recovered the bottle of topiramate from Appellant’s
    truck. The bottle indicated that the prescription had been filled the preceding day.
    The label indicated the prescription was for 30 pills with each pill containing 100
    milligrams of topiramate. Officer Egdorf counted the pills in the bottle and found
    that it contained 24 pills.
    Officer Egdorf also recovered from Appellant’s truck the medication
    information sheet for the topiramate, which Appellant had received the previous
    day. The sheet indicated that topiramate is a prescription medication used to treat
    epilepsy and migraines. It also indicated that side effects for topiramate include:
    weakness, tiredness, drowsiness, dizziness, confusion, and difficulty concentrating.
    Under the heading “precautions,” the sheet stated that topiramate “may make you
    dizzy or drowsy or cause blurred vision. Do not drive, use machinery, or do any
    6
    activity that requires alertness or clear vision until you are sure you can perform
    such activities safely.”
    Officer Egdorf transported Appellant to the hospital where a blood sample
    was drawn. The officer then transported Appellant to the police station. There,
    Officer Egdorf again administered the HGN test to Appellant. Officer Egdorf used
    a piece of equipment known as a HawkEye to make a close-up video recording of
    Appellant’s eyes while the HGN test was administered. Appellant again exhibited
    all six clues of intoxication. In addition, Officer Egdorf observed that Appellant’s
    eyes showed a lack of convergence when he brought a stimulus in toward
    Appellant’s nose.     This also indicated to Officer Egdorf that Appellant was
    intoxicated.
    Appellant was charged with two offenses of intoxication manslaughter with
    respect to the deaths of Manuel Portillo and Cristo Alfonso. Each indictment read
    as follows:
    . . . MICHAEL GREGORY PETTY, . . . on or about JULY 26, 2010,
    did then and there unlawfully by accident and mistake while operating
    a motor vehicle in a public place while intoxicated and by reason of
    that intoxication, cause the death of [the complainant], by driving his
    motor vehicle into and causing it to collide with a motor vehicle
    occupied by the complainant.
    [A]t the time that the Defendant committed the felony offense of
    INTOXICATION MANSLAUGHTER on or about JULY 26, 2010,
    as hereinabove alleged, he used and exhibited a deadly weapon,
    namely, a MOTOR VEHICLE, during the commission of said offense
    and during the immediate flight from said offense.
    7
    At trial, Appellant’s defense was two-fold. Appellant asserted that he was
    not intoxicated at the time of the collision. He claimed that the topiramate had not
    impaired his use of his mental or physical faculties. Appellant also asserted that he
    was not the cause of the collision. He claimed that there had been a mechanical
    problem with his truck. Appellant asserted that either a tire had blown out or the
    tie rod had broken, causing him to lose control of his truck and collide with
    Portillo’s vehicle.
    The State presented numerous witnesses who had seen Appellant driving on
    the freeway immediately before the collision and had witnessed the collision itself.
    They testified regarding the great speed at which Appellant drove his truck, his
    erratic driving, his zigzagging between lanes, and his darting between cars. Two
    witnesses testified that Appellant was driving so fast that their cars shook as
    Appellant sped by their vehicles. One witness stated that, at the time, she thought
    Appellant was in a high-speed chase. The witnesses indicated that the collision
    occurred when Appellant slammed on his brakes to avoid the vehicles in front of
    him, swerved to right, and lost control of his truck. A number of the witnesses
    indicated that they had not noticed anything mechanically wrong with Appellant’s
    truck, including its tires.
    The State presented evidence—through the testimony of the police officers
    who had reconstructed the collision—that Appellant had not lost control of his
    8
    truck due to a blown out tire or from a broken tie rod. Following the crash, the
    truck was found to have a broken tie rod and a flat tire, however, the State
    presented evidence showing that this damage had happened as a result of the
    collision and was not the cause of the collision. In line with the testimony of the
    eye witnesses, the State’s accident reconstruction expert testified that Appellant
    had been going at least 84 miles-an-hour.
    Appellant’s then-girlfriend, Kristen, testified that she and Appellant had
    gone to the emergency room the day before the crash because Appellant had a
    migraine headache. She stated that Appellant was released that same night around
    8:00 or 9:00 p.m. Appellant filled his prescription at the pharmacy that night, but
    Kristen did not see him take the medication that night or the next morning. Kristen
    testified that Appellant had gone to the hospital a number of other times earlier in
    the month for his migraines.
    Kristen also stated that, on the morning of the crash, Appellant had driven
    her to the restaurant where she worked. Appellant told her that he had taken a
    stool softener prescribed by the doctor the previous day. Appellant stayed at the
    restaurant for an hour or hour and-one-half until the stool softener worked. Kristen
    testified that when he left the restaurant, Appellant looked “normal” to her.
    Immediately after the crash, Appellant called Kristen on his cell phone. The
    restaurant was close to where the crash had occurred, and Kristen went to the
    9
    scene. She stated that she was able to talk to Appellant for a few minutes before he
    was placed in a patrol car. Kristen stated that Appellant appeared shaken and
    nervous but did not seem intoxicated.
    Officer Egdorf also testified at trial.    He described his interaction with
    Appellant at the scene, including Appellant’s repeated acknowledgment that he
    was aware that the topiramate warning label had an instruction not to drive after
    taking topiramate. Officer Egdorf testified that topiramate is a central nervous
    system depressant similar to alcohol. Officer Egdorf also described the field-
    sobriety tests he had administered to Appellant and explained how Appellant’s
    performance of the tests further indicated that he was intoxicated.
    With regard to the HGN test, Officer Egdorf explained that nystagmus is the
    involuntary jerking of the eye caused by a central nervous system depressant, such
    as alcohol or topiramate. Officer Egdorf testified that the nystagmus can affect a
    driver’s vision. Specifically, nystagmus may affect a driver’s ability to see out of a
    vehicle’s side and rear view mirrors and could affect a driver’s peripheral vision.
    The video taken by Officer Egdorf’s in-car camera at the scene was admitted
    into evidence during the officer’s testimony.       The video showed Appellant’s
    performance of the field sobriety tests, and it captured Appellant’s interaction with
    Officer Egdorf. When asked, Officer Egdorf agreed that Appellant had been
    cooperative during the scene investigation. He also acknowledged that Appellant
    10
    was not slurring his speech or stumbling. Aside from the HGN test, Officer Egdorf
    agreed that Appellant had correctly performed portions of the field-sobriety tests.
    He also agreed that, to the “average person,” Appellant may not have appeared
    intoxicated.
    The Hawk Eye video showing a close up of Appellant’s eyes during the
    administration of the HGN test was also admitted into evidence. As the video was
    played for the jury, Officer Egdorf pointed out the jerking of Appellant’s eyes, or
    nystagmus, seen in the video.
    Officer Egdorf acknowledged that much of his testimony offered to support
    his determination that Appellant was intoxicated related to Appellant’s
    performance on the HGN test. However, when asked to explain the basis for his
    belief that Appellant had lost the use of his physical faculties, Officer Egdorf
    responded, “We see that with the HGN tests, with the muscle control in his eyes.
    You see it on the physical test, the divided-attention test, with the clues that you
    see on the one-leg stand test, the Rhomberg balance test, the four clues that we see
    on the walk-and-turn test.”
    When asked to support his opinion that Appellant had lost the use of his
    mental faculties, Officer Egdorf responded: “I think you hear in the video with his
    repetitive speech, his story changing, he’s not able to follow all the instructions
    that I gave him. He keeps interrupting as I’m trying to give instructions.”
    11
    The State also offered the testimony of Dr. Jeff Walterschied, assistant chief
    toxicologist at the Harris County Institute of Forensic Sciences. Dr. Walterschied
    testified that topiramate is a central nervous system depressant. He stated that
    alcohol is also a central nervous system depressant. He explained that a central
    nervous system depressant affects the central nervous system by slowing neural
    firing; it causes drowsiness and loss of coordination.
    Dr. Walterschied said that topiramate is mainly used to treat epilepsy but can
    also be used to treat migraines when other treatments have failed.              Dr.
    Walterschied provided the following testimony regarding the effects of taking
    topiramate:
    Q. Now, when someone takes Topiramate or [the brand name]
    Topamax, what kinds of effects will it have on the body?
    A. It can cause dizziness, drowsiness, loss of coordination, slurred
    speech. One of the most notable effects that’s been found is cognitive
    impairment or clouded judgment.
    Q. What does cognitive impairment mean?
    A. It’s the inability to, say, remember and recall memories,
    information, making judgments. Quick decisions are impaired.
    Q. How does this impact someone’s driving abilities?
    A. Adversely.
    Q. In what ways?
    A. In the safe operation of a vehicle, you have to keep track of a
    number of things; time and speed, distance relative to other cars,
    12
    keeping track of many different things. And whenever those—under
    the influence of an intoxicating drug, the ability to keep track of
    positions of cars and of rate and speed and coordination are all
    impaired.
    Q. Now, is that true of someone that is taking a prescribed dose? Can
    they still be affected and have cognitive impairment on Topiramate?
    A. It can, yes.
    Dr. Walterscheid testified that Appellant’s blood contained 13 milligrams
    per liter (13mg/L) of topiramate. Dr. Walterscheid stated that this amount was
    much higher than expected under normal treatment for epilepsy or for migraines.
    He testified that a typical therapeutic dose of topiramate was four to five
    milligrams. He explained that a “[t]herapeutic dose would be the amount needed
    to achieve therapeutic resolution, but not too excessive to cause adverse effects.”
    With regard to the level of topiramate found in Appellant’s blood, the
    following exchange occurred:
    Q. So, typically, a therapeutic dose would be—what number would
    you be looking at?
    A. Around 4 to 5 milligrams per liter.
    Q. The 13 milligrams per liter, how much Topiramate would it take to
    get to this level?
    A. About 5 to 600 milligrams.
    Q. Now, is that 5 to 600 milligrams taken all at one time?
    A. In a short interval.
    13
    Q. What does a short interval mean?
    A. Maybe within five to ten hours.
    Q. So, if someone had a prescription filled, let’s say, at about 10:00
    p.m. for 30 hundred-milligram tablets of Topiramate and the next
    morning, around 12:30, it was discovered that six of those pills were
    missing, would that be consistent with the levels of Topiramate that
    were determined to be in the defendant’s body?
    A. Yes.
    Q. So, six 100-milligram tablets is how much Topiramate?
    A. Six hundred.
    Q. Six hundred milligrams.
    ....
    Q. Now, the level of 13 milligrams per liter, is that a therapeutic dose?
    A. It exceeds what would be a normal therapeutic level.
    Q. What—would that be an intoxicating amount?
    A. Yes.
    Dr. Walterschied also explained the meaning of a drug’s half-life. He stated,
    “Half-life is a concentration-dependent process of elimination in the body for
    certain drugs. And in this case, Topiramate has a half-life of around 20 hours. So,
    every 20 hours it goes by half and then half and then half of the original amount is
    left.” When asked how long a 100-milligram pill of topiramate would remain in a
    14
    person’s body he stated, “[A]ny drug will persist about six to seven half-lives. So,
    that would be 140 hours . . . .”
    Dr. Walterschied also testified regarding nystagmus. He stated,
    Nystagmus is a natural mechanism the body uses to track objects as
    they’re passing, especially in peripheral vision. And so, you’re—
    whenever you’re in traffic or let’s say you’re stationary watching a car
    go by, you’re really locking on and tracking it. So, if nystagmus . . . is
    enhanced, affected, it’s—you lack the ability to lock and track. And
    it’s more of . . . a wavering, so kind of a blurry, double-vision sort of
    effect.
    At the conclusion of its direct examination, the State asked: “Based on your
    experience and training and the results of this blood test, do you have an opinion as
    to whether or not the defendant was intoxicated at the time of this crash?” Dr.
    Walterschied responded, “Yes, this is intoxicating.”
    On cross-examination, defense counsel questioned Dr. Walterschied
    regarding his opinion that the 13 milligrams per liter of topiramate present in
    Appellant’s blood was an intoxicating level of topiramate and not a therapeutic
    level. Defense counsel first got Dr. Walterschied to concede that not everyone
    who takes topiramate will experience its side effects:
    Q. And in your testimony, it’s fair to say that you cannot
    conclusively state what the effects of this . . . 13 milligrams per
    liter that [the laboratory analyst] came up with, how it would
    have affected Mr. Petty in this case, correct?
    A. Well, based on my experience and training, it’s consistent
    with what is found in the medical literature.
    15
    Q. That this particular level that you all came up with had an
    intoxicating effect on Michael Petty?
    A. I can only say it’s consistent with intoxication.
    Q. Well, let me ask you this: When you talk about the side-
    effects of Topiramate, you’d agree with me that you cannot say
    that side-effects—these particular side-effects always occur,
    correct?
    A. Not always.
    ....
    Q. In other words, there’s going to be the person that doesn’t
    experience dizziness or drowsiness, correct?
    A. That can be true.
    Q. Okay. There’s going to be the person who doesn’t have
    blurred vision the way it may affect other people, correct?
    A. That’s possible.
    Q. There’s going to be the person that has . . . no serious side-
    effects, although there may be a long listing of side-effects that
    may be common, correct?
    A. True.
    Defense counsel also questioned Dr. Walterschied regarding how he
    determined that 13 milligrams per liter of topiramate was an intoxicating level
    versus a therapeutic level:
    Q. Now, you stated what you would expect for the therapeutic
    dose would be between 4 and 5, correct?
    A. About that, yeah.
    16
    Q. And the number that you-all came up with is 13, correct?
    A. Right.
    Q. And so, at what point between therapeutic and intoxicating
    levels would you draw the number? Is it 6? Is 6 all of a sudden
    intoxicating?
    A. No, . . . it’s kind of a gray area. It’s more of observations
    of—
    Q. Okay. I’m sorry. I don’t want to cut you off. Observations
    of?
    A. Observations of intoxication correlating with scientific data
    that we have.
    Q. Okay. So, observations of whom?
    A. From the police reports and witnesses.
    Q. And so, in order for you to then move it to an intoxicating
    level, you’ve got to rely on what the police officers put in the
    report, correct?
    A. That’s right.
    Q. Because you have no—I mean, you weren’t out there at the
    scene at any time, didn’t become involved in this case until
    almost a year later, correct?
    A. That’s right.
    Q. And so, you’ve got to depend on whatever the arresting
    officers or the observing officers . . . to then come in here and
    tell the jury whether or not you think it’s therapeutic or
    intoxicating, correct?
    A. Right.
    17
    Appellant testified in his own defense at trial. He stated that he had gone to
    the hospital the day before the crash because of a migraine headache. He testified
    that he was admitted as an outpatient and given Demerol intravenously for pain.
    Appellant stated that he was released from the hospital about 2:30 a.m. on the day
    of the crash with a prescription for topiramate. He said that he had already been
    taking topiramate for approximately two weeks. On his way home, he filled the
    topiramate prescription at the pharmacy. He stated that the prescription was for 30
    topiramate pills with each pill containing 100 milligrams of topiramate. Appellant
    testified that he had taken one topiramate before he went to sleep. He woke up
    around 8:15 a.m. and took another topiramate. At that point, Appellant claimed
    that 28 topiramate pills remained in the bottle. Appellant stated that he drove his
    girlfriend, Kristen, to work around 9:45 a.m. He stayed at her workplace until
    lunchtime.
    After leaving, Appellant immediately got onto Interstate 45 with his truck.
    He testified that he had taken a laxative that morning and, after entering the
    freeway, he felt that he needed to use the restroom. Appellant stated that he was
    traveling 70 miles an hour and changing lanes in attempt to reach his home to
    prevent having a bowel movement in his pants. He denied traveling at a rate of 80
    to 90 miles an hour, as a number of witnesses had stated. Appellant claimed that
    he had not been on the freeway long when his tire blew out. He stated this caused
    18
    him to lose control of the truck, and he crash into Portillo’s vehicle. Appellant
    testified that the topiramate had not affected his physical or mental faculties on the
    day of the crash. In other words, he denied that he was intoxicated.
    Following closing arguments, the jury found Appellant guilty of two
    offenses of intoxication manslaughter.
    During the punishment phase, the jury heard that Appellant had previously
    been convicted of assault, burglary of a motor vehicle, and criminal mischief.
    Appellant had also been convicted of reckless driving in 2007 because he had been
    zig-zagging between lanes and driving 90 miles per hour. Appellant’s driving
    record also showed a history of speeding tickets and getting into car accidents.
    The State also presented records obtained from Appellant’s cell phone. The
    records were from several days preceding the crash. These records included text
    messages between Appellant and numerous other people.            The text messages
    reveal that Appellant was dealing marihuana on the day of the crash. In one
    message, sent the morning of the crash, Appellant told a friend that he was
    required to take a drug class because he had failed a drug test at work. He stated
    that he had to start selling drugs to make ends meet.
    A photograph recovered from Appellant’s phone was also admitted into
    evidence. It shows Appellant in a hospital gown smiling and flashing a gang sign.
    19
    The photograph was taken the same month as the crash, during another hospital
    admission.
    Members of the complainants’ families also testified regarding the good
    character of the complainants, how much the complainants were missed, and how
    greatly their deaths had affected the families. In addition, personal photographs of
    the complainants were admitted into evidence.
    Appellant and his sister testified at the punishment phase.         They each
    testified that Appellant was remorseful, and Appellant apologized to the
    complainants’ families.     Appellant also admitted that he had been selling
    marihuana, as indicated in the text messages. Appellant admitted to causing the
    crash, but he continued to deny that he was intoxicated at the time of the collision.
    After hearing the evidence, the jury assessed Appellant’s punishment at the
    maximum sentence for each offense: 20 years in prison. The trial court ordered the
    sentences to be served consecutively. In the judgments, the trial court ordered
    Appellant to pay $444.00 in court costs.
    Appellant filed a motion for new trial in each case. Appellant claimed that
    he had received ineffective assistance of counsel at trial. He asserted that trial
    counsel “did not perform a scientific investigation into the issue of intoxication and
    did not consult or retain an expert or adequately prepare for trial.” To support the
    motion, Appellant attached an affidavit of Ed French, who holds a Ph.D. in
    20
    pharmacology. Dr. French stated that the recommended dosage of topiramate to
    treat migraines is 100 milligrams divided into two 50 milligram doses. He also
    averred as follows:
    In my search and review of a very reliable drug compendium, I could
    not find anything to support a finding of blood levels and degrees of
    intoxication. Topiramate is primarily cleared through the kidneys.
    Therefore, the blood levels of topiramate could be increased if kidney
    function has declined (which could result in involuntary overdose). If
    the defense had consulted with me or any properly trained
    pharmacologist prior to trial, they would have been able to present this
    information to the jury.
    I have been informed that Mr. Petty’s level of topiramate was 13
    mg/L. This level is within the normal therapeutic range and is not
    indicative of intoxication. My current professional understanding is
    that the therapeutic range of topiramate is 2 mg/L–20 mg/L. The
    range in which topiramate induces intoxication has not been well-
    studied or established in scientific literature. Furthermore, most
    individuals display optimal response to topiramate with serum levels 2
    mg/L–20 mg/L. Some individuals may respond well outside this
    range, or may display toxicity within the therapeutic range, thus
    interpretation should include clinical evaluation.
    The State filed a response to the motion for new trial, supported by the
    affidavit of Dr. Walterschied, who had testified at trial. In his affidavit, Dr.
    Walterschied responded to the assertions made by Dr. French in his affidavit. Dr.
    Walterscheid agreed that the recommended dose for topiramate to treat migraines
    is 100 milligrams per day administered in two divided doses. However, he stated
    that the treatment must be administered with a four-week titration plan, meaning
    that the daily doses of topiramate are increased from 25 milligrams taken in the
    21
    evening for the first week followed by an incremental increase into the fourth week
    of therapy to 100 milligrams per day.
    Dr. Walterschied stated that the dosage that Appellant claimed to have taken
    before the crash was not large enough to explain a 13mg/L level of topiramate in
    his blood. Dr. Walterscheid acknowledged that poor kidney function would be a
    significant factor if the dosing of topiramate had occurred over several days, but he
    indicated in his affidavit that was not what had occurred in this case.           Dr.
    Walterschied stated that the therapeutic range for topiramate of 2 mg/L to 20 mg/L,
    reflected in the medical literature, applied to the prevention of epilepsy rather than
    to the treatment of migraines. He also stated that “it is important to recognize that
    a therapeutic dose can still overlap with impairment. Patients who require larger
    doses to prevent onset of seizures are advised to not perform safety-critical tasks
    such as driving, particularly during the initial titration phase of therapy.”
    In his affidavit, Dr. Walterscheid set out, explained, and then applied, the
    mathematical formula he used to determine the amount of topiramate in
    Appellant’s blood. He stated that this amount was consistent with the theory that
    Appellant had taken 600 milligrams of topiramate. Dr. Walterschied averred that
    this “supports the assertion that the missing 600mg tablets from the topiramate
    prescription bottle were ingested by the defendant.”
    22
    In response to Dr. Walterscheid’s affidavit, Appellant offered the affidavit of
    Thomas Kosten, a medical doctor board certified in neurology and psychiatry. He
    averred that, although topiramate is a sedative like alcohol, it “does not make you
    feel high or euphoric.” He stated that topiramate is “often considered unpleasant
    by patients,” particularly at the dosage level prescribed to Appellant. According to
    Dr. Kosten, ingesting 600 milligrams of topiramate at one time would likely make
    a person nauseous and possibly vomit. Dr. Kosten stated that topiramate is “not
    considered a controlled or abused drug.”
    Dr. Kosten also stated that Appellant’s 13 mg/L topiramate blood level was
    “not clinically meaningful” and did not indicate that Appellant had ingested 600
    milligrams of topiramate.    Dr. Kosten averred that Appellant “has mild renal
    impairment leading to an increase in blood levels of this medication compared to
    the amount [of topiramate] ingested.” Dr. Kosten also stated that other factors
    affect the level of topiramate in a person’s blood and those factors should be
    considered. He identified timing and amount of the last dose taken and whether
    the medication had been taken acutely or chronically as factors to consider. Dr.
    Kosten noted, “Mr. Petty was taking this medication chronically and had no history
    of impairment with topiramate in the past.” Dr. Kosten concluded, “[F]or all of the
    above reasons [Dr. Walterschied’s] calculation is likely to be inaccurate and a
    significant over-estimation of the dose being taken.”
    23
    Dr. Kosten also addressed horizontal gaze nystagmus.           He stated that
    nystagmus is a normal effect caused by therapeutic dosages of topiramate. He
    acknowledged that “[n]ystagmus is one sign of several signs to be used in a
    determination of intoxication.” Dr. Kosten offered his opinion that the video of
    Appellant at the scene “showed no other evidence of intoxication or impairment.”
    Appellant’s trial counsel, Michelle Beck, also filed an affidavit regarding her
    trial preparation and strategy. In her affidavit, Beck stated her investigation had
    included personal research and reading of numerous articles on topiramate. She
    also read articles from the Internet provided by Appellant. Counsel stated that she
    reviewed literature on the effects of topiramate in DWl cases and on its prescribed
    uses. Beck stated that her next step was “to investigate whether this level of
    Topirimate was intoxicating.”      She averred that she consulted with three
    pharmacists and the emergency room doctor, who saw Appellant, “for their
    professional opinions as to the intoxicating effects this amount of the drug would
    have on [Appellant].” Beck testified that she contacted Brandon Moody, Warren
    Moody, and Lance Henderson of Texas Southern University School of Pharmacy,
    who are each licensed pharmacist and “who have expertise in the area of
    toxicology and effects of drugs on the human system.” She stated, “I discussed
    with them the findings with regard to the disclosed levels of Topiramate and was
    24
    informed that there is no set level of the drug which establishes intoxication.”3
    Beck testified that she “was told that these upper and lower levels for therapeutic
    verses intoxication limits could be manipulated based upon whomever was doing
    the analysis.”
    Beck further stated in her affidavit as follows:
    Because there was no definitive conclusion in research articles as well
    as the expert opinions of those that I spoke with concerning
    established levels of intoxication with regard to this drug, I decided it
    was not necessary to hire an expert to testify in this matter. I
    determined that I would be able to get the State’s expert witness with
    regard to toxicology to admit on cross-examination that there are no
    established levels of intoxication and no legal limits established with
    regard to Topiramate. I accomplished this with Dr. Walterschied. I
    used the State’s own witness to make my point.
    I then decided to look at what signs of intoxication the defendant
    exhibited just after the accident which would go to loss of normal use
    of mental and physical faculties. After reviewing the defendant’s
    performance at the scene and the police station, I determined that he
    performed pretty well. The normal signs of speech and a coherent
    thinking processes were present. He performed relatively well on the
    standardized field sobriety tests and I knew that the State would rely
    heavily on the HGN test which normally is not enough alone to
    convince a jury of intoxication. The State only had one witness, Ofc.
    Egdorf, who I predicted they would attempt to make their entire case
    of intoxication on. I made a strategical decision to base our defense
    on the visual evidence that the jury would be able to review with their
    own eyes. I also spoke with the defendant’s then girlfriend Kristen
    [L.], to determine what, if any signs of intoxication she observed in
    the defendant and she stated none. I also spoke with the defendant
    3
    Appellant submitted an affidavit from Henderson in which he stated that Beck had
    called him requesting information regarding topiramate to aid in Appellant’s
    defense. Henderson stated that, after he had gathered some information, he did not
    receive a call back from Beck.
    25
    about his physical and mental state at the time of the accident and
    brought that testimony out at trial regarding his level of loss of normal
    use.
    At a hearing on Appellant’s motions for new trial, the trial court admitted
    the affidavits into evidence. No live testimony was presented. At the end of the
    hearing, the trial court denied Appellant’s motions for new trial.
    These appeals followed. Appellant presents the same two issues in each
    appeal. He asserts that he received ineffective assistance of counsel at trial and
    claims that the court costs reflected in the judgments are not supported by
    sufficient evidence.
    Ineffective Assistance of Counsel
    Appellant frames his first issue as follows: “Trial counsel rendered
    ineffective assistance of counsel for failing to present an expert witness on
    topiramate and was therefore unable to offer any meaningful challenge to the
    findings and conclusions of the State’s experts, many of which proved to be
    incorrect.” Appellant summarized his arguments in his brief as follows:
    Despite the fact that counsel knew the State would argue that her
    client was intoxicated on little-known prescription medication that did
    not have well-accepted levels of intoxication, she failed to retain the
    expert assistance that was necessary in order to present a defense and
    counter the arguments made by the State’s expert witnesses. An
    expert was crucial to inform the jury as to the effects of topiramate,
    the significance of the blood levels, especially with regard to Mr.
    Petty’s kidney disorder, and the meaning of the HGN test.
    26
    ....
    The State’s experts testified unchallenged that topiramate was an
    intoxicating drug similar to alcohol and that since Mr. Petty’s blood
    levels were three times the therapeutic amount and he failed the
    HGN, he must have been legally intoxicated. Trial counsel was
    completely unable to refute these inaccurate conclusions without the
    assistance of an expert and was therefore ineffective in violation of
    [Appellant’s] rights.
    A.     Applicable Legal Principles
    To prevail on an ineffective assistance claim, an appellant must show that
    (1) his counsel’s representation fell below an objective standard of reasonableness
    and (2) the deficient performance prejudiced his defense.         See Strickland v.
    Washington, 
    466 U.S. 668
    , 669, 
    104 S. Ct. 2052
    , 2055 (1984); see also Perez v.
    State, 
    310 S.W.3d 890
    , 892–93 (Tex. Crim. App. 2010). An appellant must satisfy
    both prongs by a preponderance of the evidence; failure to demonstrate either
    deficient performance or prejudice will defeat a claim of ineffectiveness. See
    
    Perez, 310 S.W.3d at 893
    .
    Under the second Strickland prong, “[t]he defendant must show that there is
    a reasonable probability that, but for counsel’s unprofessional errors, the result of
    the proceeding would have been different.” 
    Perez, 310 S.W.3d at 893
    (quoting
    
    Strickland, 466 U.S. at 694
    , 104 S. Ct. at 2068). “A reasonable probability is a
    probability sufficient to undermine confidence in the outcome.”         Id. (quoting
    
    Strickland, 466 U.S. at 694
    , 104 S. Ct. at 2068). An appellant must show more
    27
    than “that the errors had some conceivable effect on the outcome of the
    proceeding.”   
    Id. (quoting Strickland,
    466 U.S. at 
    693, 104 S. Ct. at 2067
    ).
    “Rather, he must show that ‘there is a reasonable probability that, absent the errors,
    the factfinder would have had a reasonable doubt respecting guilt.’” 
    Id. (quoting Strickland,
    466 U.S. at 
    695, 104 S. Ct. at 2068
    –69). A “reasonable probability” is
    a probability sufficient to undermine confidence in the outcome. See Andrews v.
    State, 
    159 S.W.3d 98
    , 102 (Tex. Crim. App. 2005).
    When, as here, the prejudice prong of the Strickland test is dispositive, we
    need address only that prong on appeal. See My Thi Tieu v. State, 
    299 S.W.3d 216
    ,
    225 (Tex. App.—Houston [14th Dist.] 2009, pet. ref’d) (citing 
    Strickland, 466 U.S. at 697
    , 104 S. Ct. at 2069). And, when, as here, the ineffective assistance claim is
    asserted by a defendant in a motion for new trial, and that motion is denied after an
    evidentiary hearing, we review the denial of the motion under an abuse of
    discretion standard. See Anderson v. State, 
    193 S.W.3d 34
    , 39 (Tex. App.—
    Houston [1st Dist.] 2006, pet. ref’d). We review de novo the trial court’s decision
    on the prejudice prong while giving deference to the trial court’s implied resolution
    of underlying factual determinations in support of the denial of the motion for new
    trial. Johnson v. State, 
    169 S.W.3d 223
    , 239 (Tex. Crim. App. 2005) (quoting
    Charles v. State, 
    146 S.W.3d 204
    , 213 (Tex. Crim. App. 2004), superseded by
    TEX. R. APP. P. 21.8(b) (amended 2007)). When no express fact findings are made
    28
    by the trial court, appellate courts should “impute implicit factual findings that
    support the trial judge’s ultimate ruling on that motion when such implicit factual
    findings are both reasonable and supported in the record.” 
    Id. B. Analysis
    On appeal, Appellant asserts, “If counsel had acted as a reasonable attorney
    facing a case that hinged upon the effects of an unusual and nonscheduled
    medication, she would have retained an expert. An expert would have explained
    the effects of topiramate, the significance of the blood levels, and the meaning of
    the HGN test.” We ask: If trial counsel had presented such evidence is there a
    reasonable probability that the outcome of the proceeding would have been
    different?
    The HGN Evidence
    Appellant points out, “The HGN was a major point of evidence for the
    State.” He asserts that his trial counsel was ineffective because “the jury was never
    informed that normal, therapeutic levels of topiramate would also cause HGN, as
    Dr. Kosten’s affidavit asserts.” However, Dr. Kosten also acknowledged in his
    affidavit that “the presence of nystagmus can signify some aspects of intoxication.”
    Indeed, the Court of Criminal Appeals held in Emerson v. State that the HGN test
    is a reliable indicator of intoxication. 
    880 S.W.2d 759
    , 777 (Tex. Crim. App.
    29
    1994). Here, Officer Egdorf testified that Appellant exhibited all six clues of
    intoxication on the HGN test.
    Appellant also criticizes trial counsel because she “did not challenge the
    repeated assertion that HGN equates with blurred vision and proves intoxication.”
    In support of his criticism, Appellant cites a publication by the National Highway
    Traffic Safety Administration, entitled “Horizontal Gaze Nystagmus: The Science
    & The Law–A Resource Guide for Judges, Prosecutors and Law Enforcement.” 4
    The publication states, “Most types of nystagmus, including HGN, are
    involuntary motions, meaning the person exhibiting the nystagmus cannot control
    it. In fact, the subject exhibiting the nystagmus is unaware that it is happening
    because the bouncing of the eye does not affect the subject’s vision.” 5 However, a
    footnote to the last sentence in the quote states, “There have been some studies that
    suggest that HGN due to alcohol impairment may affect the ability of a person to
    see clearly.” 6 At trial, the State presented evidence that topiramate and alcohol are
    both classified as depressants, which affect the central nervous system. In his
    affidavit offered to support Appellant’s motion for new trial, Dr. Kosten
    4
    The publication Horizontal Gaze Nystagmus: The Science & The Law–A Resource
    Guide for Judges, Prosecutors and Law Enforcement is available at
    http://www.nhtsa.gov/people/injury/enforce/nystagmus/hgntxt.html (last visited
    June 8, 2014).

    Id. 6 Id.

    acknowledged that topiramate is a sedative like alcohol. Given the footnote and
    the evidence, Appellant has not shown that he would have benefitted from a
    challenge to the State’s evidence that HGN equates with blurred vision.
    In addition, it is significant that ample evidence of Appellant’s intoxication,
    aside from the HGN evidence, was presented at trial. The jury in this case was
    correctly instructed, “‘Intoxicated’ means not having the normal use of mental or
    physical faculties by reason of the introduction of alcohol, a controlled substance, a
    drug, a dangerous drug, a combination of two or more of those substances, or any
    other substance into the body.”         See TEX. PENAL CODE ANN. § 49.01(2)(A)
    (Vernon 2011).
    Numerous witnesses testified that he or she saw Appellant driving in an
    alarming and erratic manner at a high rate of speed.           The State’s accident
    reconstruction expert testified that Appellant was driving at least 84 miles-an-hour,
    while darting between cars and zigzagging between lanes. When he approached
    slower moving traffic, witnesses stated that Appellant had slammed on his brakes,
    swerved right across the freeway, lost control, and crashed into Portillo’s truck.
    The State offered evidence showing that the crash had not been caused by a blown
    out tire or broken tie rod, as Appellant testified at trial.
    In addition to the HGN test, Officer Egdorf testified that Appellant displayed
    clues of intoxication on the three other field-sobriety-tests. Significantly, on the
    31
    Rhomberg test, Appellant estimated the passage of 46 seconds to be the passage of
    30 seconds.    Officer Egdorf testified that this indicated to him a delay in
    Appellant’s reaction time. Officer Egdorf also testified that Appellant displayed
    four clues for intoxication during the walk-and-turn test and one clue when he
    swayed during the one-leg-stand test.
    Officer Egdorf further stated that he observed signs that Appellant’s mental
    faculties were impaired.     Officer Egdorf testified that Appellant continually
    interrupted him while he was instructing Appellant how to perform the field
    sobriety tests. He stated that Appellant had difficulty following those instructions.
    Officer Egdorf also noted that Appellant’s statements regarding what may have
    caused the crash continued to shift as he and Appellant spoke.
    The jury also heard Appellant, in the scene video, admit to Officer Egdorf
    that the topiramate label had a warning not to drive while taking the medication.
    Appellant stated that he had taken one 100 milligram topiramate after he left the
    hospital at 2:30 a.m. and another when he awoke at 8:15 a.m. The collision
    occurred at approximately at 12:30 p.m.
    The drug information sheet, recovered from Appellant’s truck and admitted
    into evidence, warned that the side effects for topiramate include: weakness,
    tiredness, drowsiness, dizziness, confusion, and difficulty concentrating. Under
    the heading “precautions,” the sheet stated that topiramate “may make you dizzy or
    32
    drowsy or cause blurred vision. Do not drive, use machinery, or do any activity
    that requires alertness or clear vision until you are sure you can perform such
    activities safely.”
    Dr. Walterscheid also testified that topiramate can cause dizziness,
    drowsiness, and loss of coordination. He stated that one of the most notable effects
    is cognitive impairment or clouded judgment. Dr. Walterscheid explained that
    cognitive impairment adversely affects a person’s ability to drive. He explained,
    In the safe operation of a vehicle, you have to keep track of a number
    of things; time and speed, distance relative to other cars, keeping track
    of many different things. . . . [U]nder the influence of an intoxicating
    drug, the ability to keep track of positions of cars and of rate and
    speed and coordination are all impaired.
    Dr. Walterscheid testified that cognitive impairment may occur even when a
    person is taking a prescribed dose of topiramate.
    Furthermore, the State presented evidence that the pill bottle recovered from
    Appellant’s truck contained only 24 of the 30 prescribed pills.             This was
    circumstantial evidence from which the jury could have inferred that Appellant had
    taken six pills, rather than the two pills that he claimed to have taken. Lastly, the
    blood test showed that Appellant had topiramate in his system. In short, there was
    ample evidence of Appellant’s intoxication, aside from the HGN evidence.
    Appellant has failed to show that he was prejudiced by his trial counsel’s handling
    of the HGN evidence.
    33
    Topiramate Blood Levels
    Appellant also criticizes trial counsel because she did not retain an expert to
    refute Dr. Walterschied’s testimony (1) that the therapeutic level of topiramate was
    not limited to 4 to 5 mg/L and (2) that Appellant’s blood level of 13 mg/L
    exceeded a normal therapeutic level to the point it was an intoxicating level. As
    she stated in her affidavit, trial counsel decided not to retain an expert to show that
    there is no set intoxicating level of topiramate; rather, she made the strategic
    decision to use the State’s expert, Dr. Walterscheid, to make this point.
    As set out above, the following exchange occurred between trial counsel and
    Dr. Walterscheid during cross-examination:
    Q. Now, you stated what you would expect for the therapeutic
    dose would be between 4 and 5, correct?
    A. About that, yeah.
    Q. And the number that you-all came up with is 13, correct?
    A. Right.
    Q. And so, at what point between therapeutic and intoxicating
    levels would you draw the number? Is it 6? Is 6 all of a sudden
    intoxicating?
    A. No, . . . it’s kind of a gray area. It’s more of observations
    of—
    Q. Okay. I’m sorry. I don’t want to cut you off. Observations
    of?
    34
    A. Observations of intoxication correlating with scientific data
    that we have.
    Q. Okay. So, observations of whom?
    A. From the police reports and witnesses.
    Q. And so, in order for you to then move it to an intoxicating
    level, you’ve got to rely on what the police officers put in the
    report, correct?
    A. That’s right.
    Q. And so, you’ve got to depend on whatever the arresting
    officers or the observing officers . . . to then come in here and
    tell the jury whether or not you think it’s therapeutic or
    intoxicating, correct?
    A. Right.
    By her cross-examination, trial counsel highlighted that Dr. Walterscheid’s
    opinion regarding therapeutic blood level versus intoxicating blood level was
    dependent on the observations of Appellant’s behavior by law enforcement officers
    and witnesses. It was not based solely on the amount of topiramate found in
    Appellant’s blood. This acknowledgement by Walterscheid had the potential to
    undermine his credibility with the jury regarding his earlier testimony, on direct
    examination, which gave the impression that what constituted a therapeutic level
    and what constituted an intoxicating level was a fixed amount, based solely on the
    level of topiramate in a person’s blood.         Obtaining this testimony from
    Walterscheid was arguably more detrimental to the State’s case than obtaining it
    35
    from a defense witness hired to refute Dr. Walterscheid’s opinion. And it was a
    more effective means to let the jury know that there is no set intoxicating level for
    topiramate. Although the State mentioned in its closing argument that Appellant’s
    topiramate blood level was three times the therapeutic level, defense counsel
    pointed out in her closing statement that Dr. Walterscheid admitted on cross-
    examination that there was no clear cut-off between therapeutic and intoxicating
    topiramate blood levels.
    In addition to his concession regarding blood levels, Dr. Walterscheid also
    acknowledged on cross-examination that some people do not experience any side
    effects from topiramate.      This acknowledgment from Walterscheid served to
    diminish the importance of his other testimony regarding topiramate blood levels.
    It also corresponded with Appellant’s claim that his physical and mental faculties
    were unaffected by topiramate. It supported the defense’s strategy to focus on that
    claim.     In sum, the record does not show that Appellant was prejudiced by
    counsel’s decision not to retain an expert to address issues relating to topiramate
    blood level.
    Amount of Topiramate Taken by Appellant
    Appellant also avers that trial counsel should have retained an expert to
    assist in countering the State’s assertion that Appellant had taken six topiramate
    tablets instead of two, as he claimed. Dr. Walterscheid testified that Appellant’s
    36
    topiramate blood level of 13 mg\L was consistent with having ingested six
    topiramate tablets, the amount missing from the prescription bottle. Appellant
    points to Dr. Kosten’s affidavit in which the doctor averred, “[Dr. Walterscheid’s]
    calculation is likely an over-estimation of the dose taken.” Dr. Kosten explained
    that Appellant has a “mild renal impairment leading to an increase in blood levels
    of this medication compared to the amount ingested.” Appellant asserts that trial
    counsel should have retained expert assistance to show that Appellant’s topiramate
    blood level did not necessarily correspond to ingesting six pills but could have
    resulted from a “false” elevation of his topiramate blood level resulting from his
    mild kidney impairment.
    Even if counsel had presented evidence to refute Dr. Walterscheid’s
    conclusion that his blood level indicated that Appellant had ingested 600
    milligrams of topiramate, no evidence was offered to explain why the prescription
    bottle recovered by Officer Egdorf contained only 24 pills; that is, to show why
    600 milligrams of topiramate was missing from the bottle.         This alone was
    evidence that Appellant had taken six topiramate tablets since filling the
    prescription less than a day before the crash.
    Appellant also asserts that trial counsel should have offered evidence to
    show that, despite the State’s comparison of topiramate to alcohol, topiramate is
    not a drug that produces a “high” and does not have euphoric effect. Appellant
    37
    points out that Dr. Kosten testified that “[d]rug abusers do not like taking this
    medication due to its side effects and lack of pleasant properties.”7 Appellant
    intimates that this information would have cast doubt on the State’s theory that
    Appellant had ingested 600 milligrams of topiramate.
    With respect to the jury’s determination of guilt, the issue was not whether
    Appellant had ingested six pills or two pills; and it was not whether Appellant had
    taken topiramate to get high or whether he had taken it to keep his migraines at
    bay. Cf. Farmer v. State, No. PD–1620–12, 
    2013 WL 5538876
    , at *5 (Tex. Crim.
    App. Oct. 9, 2013) (stating that driving while intoxicated is a strict liability crime,
    not requiring a specific mental state). The issue was whether he was intoxicated.
    Even if counsel had offered expert testimony to cast doubt on the State’s theory
    that Appellant had taken six pills, the State presented ample evidence, as discussed
    above, demonstrating that Appellant was intoxicated. Thus, Appellant has failed to
    show that “‘there is a reasonable probability that, absent the errors, the factfinder
    would have had a reasonable doubt respecting guilt.’” See 
    Perez, 310 S.W.3d at 893
    (quoting 
    Strickland, 466 U.S. at 695
    , 104 S. Ct. at 2068–69).
    7
    Appellant also points out that Dr. Kosten stated in his affidavit that ingesting a 600
    milligram dose of topiramate would likely make someone nauseous and possibly
    vomit. Appellant testified that he vomited in a patrol car at the scene when he saw
    Portillo’s body. Eliciting testimony from an expert that 600 milligrams of
    topiramate would likely cause nausea had the potential to undermine Appellant’s
    claim that he became upset when he saw Portillo’s body. Rather than assisting
    Appellant, such testimony may have served instead to reinforce the State’s claim
    that Appellant had ingested 600 milligrams of topiramate.
    38
    Appellant also asserts that, even if counsel’s failure to retain an expert to
    cast doubt on the State’s claim that Appellant ingested 600 milligrams of
    topiramate did not affect the verdict, such failure likely affected the maximum
    sentence assessed by the jury.      Appellant claims that, by suggesting that he
    intentionally overdosed on topiramate, he was made to appear more culpable than
    if he had been following his doctor’s instructions with respect to dosage.
    After reviewing the record, we disagree that there is a reasonable probability
    that any deficiency by counsel to retain an expert to refute the State’s claim that
    Appellant ingested 600 milligrams of topiramate affected Appellant’s sentence. As
    discussed, the jury heard testimony from numerous eye witnesses that, before the
    crash, Appellant was driving at a high rate of speed and handling his vehicle in an
    aggressive and erratic manner.      The jury saw the scene video and observed
    Appellant’s demeanor and seeming lack of concern for the crash victims. The jury
    also saw the photographs from the autopsies and the crash scene, including
    photographs of Portillo’s head pinned between the roof and door of his truck.
    During the punishment phase, the jury heard from the complainants’ families
    that they were both good, hard-working family men, who were greatly loved and
    missed by their wives and children. In contrast, the jury also heard evidence that
    Appellant had recently tested positive at work for drug use and was admittedly a
    drug dealer.
    39
    Additionally, the jury learned that Appellant not only had a history of
    speeding and car accidents, he had previously been convicted of reckless driving.
    In committing that offense, Appellant had been driving 90 miles an hour and
    zigzagging in between lanes, facts also present in this case. The jury also learned
    that Appellant had previous convictions for assault, burglary of a motor vehicle,
    and criminal mischief. Although he apologized to the complainants’ families and
    admitted to causing the crash, Appellant continued to deny at the punishment phase
    that he had been intoxicated, despite the jury’s guilty verdicts.
    We conclude that Appellant has not shown that he was prejudiced by
    counsel’s alleged deficiencies; that is, he has not shown that there is “a reasonable
    probability that, but for counsel’s unprofessional errors, the result of the
    proceeding would have been different.” See 
    Perez, 310 S.W.3d at 893
    (citing
    
    Strickland, 466 U.S. at 694
    , 104 S. Ct. at 2068). Appellant has failed to meet his
    burden to show he received ineffective assistance of counsel. The trial court did
    not abuse its discretion by denying his motion for new trial.
    We overrule Appellant’s first issue in each appeal.
    Assessment of Court Costs
    In his second issue, Appellant asserts that the evidence was not sufficient to
    support the trial court’s assessment of $444 in court costs in the judgments.
    40
    A supplemental clerk’s record has been filed, containing a certified, signed
    bill of costs listing $444 in court costs. We review the assessment of court costs on
    appeal to determine if there is a basis for the costs, not to determine whether there
    was sufficient evidence offered at trial to prove each cost. See Johnson v. State,
    No. PD–0193–13, 
    2014 WL 714736
    , at *2 (Tex. Crim. App. Feb. 26, 2014).
    Traditional sufficiency-of-the-evidence standards of review do not apply to this
    review. 
    Id. Generally, a
    bill of costs must (1) contain the items of cost, (2) be signed by
    the officer who charged the cost or the officer who is entitled to receive payment
    for the cost, and (3) be certified. 
    Id. at *5;
    see TEX. CRIM. PROC. CODE ANN. arts.
    103.001, 103.006 (Vernon 2006).         Here, the bill of costs contained in the
    supplemental clerk’s record identifies each item of cost, is signed by a
    representative of the district clerk’s office, who is entitled to receive payment of
    the costs, and is certified. See Johnson, 
    2014 WL 714736
    at *4. There being no
    challenge to any specific cost assessed, the bill of costs supports the assessment of
    the court costs in the judgments. See 
    id. at *8.
    We overrule Appellant’s second issue in each appeal.
    41
    Conclusion
    We affirm the judgment of the trial court in each appellate cause.
